Guidelines For The Definition Of Managed Objects
The Guidelines for the Definition of Managed Objects (GDMO) is a specification for defining managed objects of interest to the Telecommunications Management Network for use in CMIP. GDMO to the Structure of Management Information for defining a management information base for SNMP. For example, both represent a hierarchy of managed objects and use ASN.1 for syntax. GDMO is defined in ISO/IEC 10165 and ITU-T The ITU Telecommunication Standardization Sector (ITU-T) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU).

Managed Object
In telecommunication, the term managed object has the following meanings: 1. In a network, an abstract representation of network resources that are managed. With "representation", we mean not only the actual device that is managed, but also the device driver, that communicates with the device. An example of a printer as a managed object is the window that shows information about the printer, such as the location, printer status, printing progress, paper choice, and printing margins. The database, where all managed objects are stored, is called Management Information Base. In contrast with a CI, a managed object is "dynamic" and communicates with other network resources that are managed. ''Note:'' A managed object may represent a physical entity, a network service, or an abstraction of a resource that exists independently of its use in management. 2. In telecommunications management, a resource within the telecommunications environment that may be managed through the use of op ...

Telecommunications Management Network
The Telecommunications Management Network is a protocol model defined by ITU-T for managing open systems in a communications network. It is part of the ITU-T Recommendation series M.3000 and is based on the OSI management specifications in ITU-T Recommendation series X.700. TMN provides a framework for achieving interconnectivity and communication across heterogeneous operations system and telecommunication networks. To achieve this, TMN defines a set of ''interface points'' for elements which perform the actual communications processing (such as a call processing switch) to be accessed by elements, such as management workstations, to monitor and control them. The standard interface allows elements from different manufacturers to be incorporated into a network under a single management control. For communication between Operations Systems and NEs (Network Elements), it uses the Common management information protocol (CMIP) or Mediation devices when it uses Q3 interface. The TM ...

Common Management Interface Protocol
The Common Management Information Protocol (CMIP) is the OSI specified network management protocol. Defined iITU-T Recommendation X.711, ISO/IEC International Standard 9596-1 It provides an implementation for the services defined by the Common Management Information Service (CMIS) specified iITU-T Recommendation X.710, ISO/IEC International Standard 9595 allowing communication between network management applications and management agents. CMIS/CMIP is the network management protocol specified by the ISO/ OSI Network management model and is further defined by the ITU-T in the X.700 series of recommendations. CMIP models management information in terms of managed objects and allows both modification and performing actions on managed objects. Managed objects are described using GDMO (Guidelines for the Definition of Managed Objects), and can be identified by a distinguished name (DN), from the X.500 directory. CMIP also provides good security (support authorization, access co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structure Of Management Information
In computing, the Structure of Management Information (SMI), an adapted subset of ASN.1, operates in Simple Network Management Protocol (SNMP) to define sets ("modules") of related managed objects in a Management Information Base A management information base (MIB) is a database used for managing the entities in a communication network. Most often associated with the Simple Network Management Protocol (SNMP), the term is also used more generically in contexts such as in ... (MIB). SMI subdivides into three parts: module definitions, object definitions, and notification definitions. * Module definitions are used when describing information modules. An ASN .1 macro, MODULE-IDENTITY, is used to concisely convey the semantics of an information module. * Object definitions describe managed objects. An ASN.1 macro, OBJECT-TYPE, is used to concisely convey the syntax and semantics of a managed object. * Notification definitions (aka "traps") are used when describing unsolicited tr ...

Management Information Base
A management information base (MIB) is a database used for managing the entities in a communication network. Most often associated with the Simple Network Management Protocol (SNMP), the term is also used more generically in contexts such as in OSI/ISO Network management model. While intended to refer to the complete collection of management information available on an entity, it is often used to refer to a particular subset, more correctly referred to as MIB-module. Objects in the MIB are defined using a subset of Abstract Syntax Notation One (ASN.1) called "Structure of Management Information Version 2 (SMIv2)" . The software that performs the parsing is a MIB compiler. The database is hierarchical (tree-structured) and each entry is addressed through an object identifier (OID). Internet documentation RFCs discuss MIBs, notably , "Structure and Identification of Management Information for TCP/IP based internets", and its two companions, , "Management Information Base for N ...

Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behaviour. Devices that typically support SNMP include cable modems, routers, switches, servers, workstations, printers, and more. SNMP is widely used in network management for network monitoring. SNMP exposes management data in the form of variables on the managed systems organized in a management information base (MIB) which describe the system status and configuration. These variables can then be remotely queried (and, in some circumstances, manipulated) by managing applications. Three significant versions of SNMP have been developed and deployed. SNMPv1 is the original version of the protocol. More recent versions, SNMPv2c and SNMPv3, feature improvements in performance, flexibility and security. SNMP is a component of the Internet Protocol Suite as defined by the I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abstract Syntax Notation One
Abstract Syntax Notation One (ASN.1) is a standard interface description language for defining data structures that can be serialized and deserialized in a cross-platform way. It is broadly used in telecommunications and computer networking, and especially in cryptography. Protocol developers define data structures in ASN.1 modules, which are generally a section of a broader standards document written in the ASN.1 language. The advantage is that the ASN.1 description of the data encoding is independent of a particular computer or programming language. Because ASN.1 is both human-readable and machine-readable, an ASN.1 compiler can compile modules into libraries of code, codecs, that decode or encode the data structures. Some ASN.1 compilers can produce code to encode or decode several encodings, e.g. packed, BER or XML. ASN.1 is a joint standard of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) in ITU-T Study Group 17 and ISO/IEC, orig ...
